System and method for providing health safety in a wireless power transmission system
First Claim
1. A method for controlling wireless transmission of power in accordance with safety restrictions, comprising:
- receiving, via an application executing on an electronic device that is coupled to a wireless power receiver, user-selected safety restrictions used to determine when wirelessly delivered power may be transmitted to the wireless power receiver;
determining, using data provided by a sensor of the electronic device, whether any of the safety restrictions are present at the electronic device;
upon determining that the safety restrictions are not present at the electronic device, receiving radio frequency (RF) power waves that are sent to the electronic device by a wireless power transmitter, wherein the wireless power transmitter only transmits the RF power waves when the safety restrictions are not present at the electronic device; and
while receiving the RF power waves;
continuing to determine whether any of the safety restrictions are present at the electronic device; and
upon determining that at least one of the safety restrictions is present at the electronic device, ceasing to receive the RF power waves from the wireless power transmitter.

Abstract
The embodiments described herein include a transmitter that transmits a power transmission signal (e.g., radio frequency (RF) signal waves) to create a three-dimensional pocket of energy. At least one receiver can be connected to or integrated into electronic devices and receive power from the pocket of energy. The transmitter can locate the at least one receiver in a three-dimensional space using a communication medium (e.g., Bluetooth technology). The transmitter generates a waveform to create a pocket of energy around each of the at least one receiver. The transmitter uses an algorithm to direct, focus, and control the waveform in three dimensions. The receiver can convert the transmission signals (e.g., RF signals) into electricity for powering an electronic device. Accordingly, the embodiments for wireless power transmission can allow powering and charging a plurality of electrical devices without wires.
